Ivalve yebhola ye-pneumatic luhlobo lwe-actuator yomoya esetyenziswa ngokubanzi kwinkqubo yolawulo oluzenzekelayo lwangoku. Umqondiso wokulawula uqhuba isenzo sokutshintsha ivalve yebhola ngokusebenzisa i-actuator ye-pneumatic ukugqiba ulawulo lokutshintsha okanye uhlengahlengiso oluphakathi kumbhobho.
Inqaku lokuqala: ukhetho lwevalve yebhola
Imowudi yoqhagamshelo: uqhagamshelo lweflange, uqhagamshelo lwe-clamp, uqhagamshelo lwentambo yangaphakathi, uqhagamshelo lwentambo yangaphandle, uqhagamshelo olukhawulezayo lwendibano, uqhagamshelo oludityanisiweyo (uqhagamshelo lwe-butt welding, uqhagamshelo lwe-socket welding)
Ukutywinwa kwesihlalo sevalve: ivalve yentsimbi eqinileyo etywiniweyo, oko kukuthi, umphezulu wokutywina wesihlalo sevalve kunye nomphezulu wokutywina webhola yintsimbi ukuya kwivalve yebhola yentsimbi. Ifanelekile kwiqondo lokushisa eliphezulu, eliqulethe iincinci eziqinileyo, ukuxhathisa ukugqoka. Ivalve yebhola ethambileyo, isitulo esisebenzisa i-polytetrafluoroethylene PTFE, i-para-polystyrene PPL imathiriyeli yokutywina elastic, isiphumo sokutywina silungile, sinokufikelela kwi-zero ukuvuza.
Izinto zeValve: I-WCB cast steel, intsimbi ephantsi yobushushu, intsimbi ye-stainless 304,304L, 316,316L, intsimbi ye-duplex, i-titanium alloy, njl.
Ubushushu bokusebenza: ivalve yebhola yobushushu eqhelekileyo, -40℃ ~ 120℃. Ivalve yebhola yobushushu obuphakathi, 120 ~ 450℃. Ivalve yebhola yobushushu obuphezulu, ≥450℃. Ivalve yebhola ephantsi yobushushu -100 ~ -40℃. Ivalve yebhola yobushushu obuphantsi kakhulu ≤100℃.
Uxinzelelo olusebenzayo: ivalve yebhola ephantsi, uxinzelelo lwe-PN≤1.6MPa. Ivalve yebhola yoxinzelelo oluphakathi, uxinzelelo lwegama 2.0-6.4MPa. Ivalve yebhola yoxinzelelo oluphezulu ≥10MPa. Ivalve yebhola efunxayo, ingaphantsi kunomoya omnye ivelufa yebhola yoxinzelelo.
Ulwakhiwo: ivalve yebhola edadayo, ivalve yebhola esisigxina, ivalve yebhola engu-V, ivalve yebhola ejikelezayo ejikelezayo
Ifom yetshaneli equkuqelayo: ngevalve yebhola, ivalve yebhola eneendlela ezintathu (i-L-channel, i-T-channel), ivalve yebhola eneendlela ezine
Inqaku lesibini: ukhetho lwe-pneumatic actuator
I-piston esebenza kabini yohlobo lwe-pneumatic actuator ikakhulu yenziwe nge-cylinder, i-cover cover kunye nepiston. Ishafu yegiya. Ibhlokhi yokukhawulela, isikrufu sokulungelelanisa, isalathisi kunye nezinye iindawo. Sebenzisa umoya ocinezelweyo njengamandla okutyhala intshukumo yepiston. I-piston idityaniswe kwi-rack ukuze iqhube i-shaft yegiya ukujikeleza i-90 °, kwaye emva koko iqhube i-valve ye-valve yokutshintsha isenzo.
I-piston-acting enye yohlobo lwe-pneumatic actuator ikakhulu yongeza umthombo wokubuya phakathi kwepiston kunye ne-cap yokuphela, enokuxhomekeka kumandla okuqhuba entwasahlobo ukuseta kwakhona ivalve yebhola kwaye ugcine indawo ivulekile okanye ivaliwe xa uxinzelelo lomthombo womoya lunempazamo. , ukuze kuqinisekiswe ukhuseleko lwenkqubo yenkqubo. Ngoko ke, ukukhethwa kweesilinda ezibambeleyo kukukhetha ukuba i-valve yebhola ivulekile okanye ivalwe ngokuqhelekileyo.
Iindidi eziphambili zeesilinda ziyi-cylinders ze-GT, iisilinda ze-AT, iisilinda ze-AW njalo njalo.
I-GT ivele ngaphambili, i-AT yi-GT ephuculweyo, ngoku iyimveliso yesiqhelo, inokufakwa ngesibiyeli sevalve yebhola simahla, ngokukhawuleza kunofakelo lwesibiyeli, ilula, kodwa iqine ngakumbi. Isikhundla se-0 ° kunye ne-90 ° sinokuhlengahlengiswa ukuze kuququzelele ukufakwa kwee-valve ezahlukeneyo ze-solenoid, ukutshintsha kwe-stroke, izixhobo ze-handwheel. I-AW cylinder isetyenziselwa ubukhulu becala ivalve yebhola ebubanzi obunamandla amakhulu kwaye yamkele ubume befolokhwe yepiston.
Inqaku lesithathu: ukukhethwa kwezixhobo ze-pneumatic
Ivalve ye-Solenoid: I-cylinder esebenza kabini ixhotyiswe ngokubanzi ngeevalvu ezimbini ze-solenoid ezineendlela ezintlanu okanye ezintathu ezineendlela ezintlanu ze-solenoid. I-cylinder enye esebenzayo inokuxhotyiswa ngeevalvu ezimbini ze-solenoid ezimbini. I-Voltage inokukhetha i-DC24V, i-AC220V njalo njalo. Kufuneka kuthathelwe ingqalelo iimfuno zobungqina bokudubula.
Ukutshintsha kwe-Stroke: Umsebenzi kukuguqula ukujikeleza kwe-actuator kwisignali yoqhagamshelwano, isiphumo kwisixhobo sokulawula, kunye nengxelo yesimo sokuvala i-valve yebhola yebala. Ngokuqhelekileyo kusetyenziswa oomatshini, uhlobo lwe-magnetic induction. Kufuneka kuqwalaselwe iimfuno zokuthintela uqhushumbo.
Indlela ye-Handwheel: efakwe phakathi kwevalve yebhola kunye ne-cylinder, inokutshintshwa kwi-manual switch xa umthombo womoya ungalunganga ukuqinisekisa ukhuseleko lwenkqubo kwaye ungalibazisi ukuveliswa.
Amacandelo okusebenza komthombo womoya: kukho iziqhagamshelo ezimbini nezintathu, umsebenzi wokuhluza, ukunciphisa uxinzelelo, inkungu yeoli. Kucetyiswa ukuba kufakwe i-cylinder ukukhusela i-cylinder ukuba ibambelele ngenxa yokungcola.
Ivalve yendawo: Kulungelelwaniso lwevalve yebhola yepneumatic kufuneka ifakwe, isetyenziswa kakhulu kwivalve yebhola yohlobo lwe-V. Ngena 4-20
mA, ukuqwalasela ukuba kukho isignali yemveliso yengxelo. Ingaba ubungqina bokudubula buyimfuneko. Kukho uhlobo oluqhelekileyo, uhlobo olukrelekrele.
Ivalve yokukhupha ngokukhawuleza: khawulezisa isantya sokutshintsha ivalve yebhola yepneumatic. Ukufakwa phakathi kwe-cylinder kunye ne-solenoid valve, ukwenzela ukuba igesi kwi-cylinder ingadluli kwi-valve ye-solenoid, ikhutshwe ngokukhawuleza.
I-Pneumatic amplifier: Ifakwe kwindlela yomoya kwi-cylinder ukufumana uphawu loxinzelelo lwe-positioner outlet, unikeze ukuhamba okukhulu kwi-actuator, esetyenziselwa ukuphucula isantya sesenzo sevalve. 1: 1 (umlinganiselo wesignali kwimveliso). Isetyenziselwa ikakhulu ukuhambisa imiqondiso ye-pneumatic kumgama omde (i-0-300 yeemitha) ukunciphisa impembelelo ye-lag yokudluliselwa.
Ivalve yokubamba umoya: Ikakhulu isetyenziselwa ukusebenza okudityanisiweyo koxinzelelo lomthombo womoya, kwaye xa uxinzelelo lomthombo womoya lungaphantsi kunoko, umbhobho wegesi wobonelelo lwevalve uyanqunyulwa, ukuze isivalo sigcine indawo phambi kokusilela komthombo womoya. Xa uxinzelelo lomthombo womoya lubuyiselwa, ukunikezelwa komoya kwi-cylinder kuqaliswa kwakhona ngexesha elifanayo.
Ukukhetha i-valve yebhola ye-pneumatic ukuqwalasela izinto ze-valve yebhola, i-cylinder, izixhobo, ukhetho ngalunye lwephutha, luya kuba nefuthe ekusebenziseni i-valve yebhola ye-pneumatic, ngamanye amaxesha amancinci. Ngamanye amaxesha iimfuno zenkqubo azikwazi ukuhlangabezana nazo. Ngoko ke, ukhetho kufuneka luqaphele iiparamitha zenkqubo kunye neemfuno.
